Is there any way to use debugger after launching Lua/Löve from a .cmd script?

My situation: I set up a simple External Run Configuration by using the Program template; setting the Location to a Windows batch located in a .cmd file and the Working directory to its location. This script has a bunch of custom path settings, executable calls, and ultimately calls the Löve interpreter. Everything works fine, but now how to actually run the debugger?

Alternatively, would it be easier to reconfigure the project, setting the environment up within Eclipse and then manually setting up Löve as an external interpreter? I know that it is not officially supported, but people seem to have gotten it to. The instructions aren't completely clear and I haven't been successful.
